System for membrane removal and transfer

A filter removal apparatus for removal of microporous filter membranes from multi-well filtration plate comprises a removal device and a pusher having defined therein a plurality of vertical pushpins. The pusher has a leading pushing surface to which elongated pushpins are secured each having a flat face to deliver an even pressure onto the filter membrane. The removal device comprises a stationary base plate with end wall and side walls holding a pivotal cylindrical bar which rotates in eccentric manner along its longitudinal axis. Rotation of cylindrical bar using attached handle approximately 180 degrees around the longitudinal center-line of pivot shafts causes the cylindrical bar to rotate in an eccentric motion, thus imparting a linear force to a moving plate which forces the pusher into the filter plate and causing removal of filter membranes and their flattening onto adhesive film for retention.
